The board has DDR3 512MB. This patch helps scanning the memory and
adding memblock through the DT.

Right, my intention was adding memblock through the DT whether the
bootload does or not. However I'm not sure the situation (missing
memblock in u-boot) could really happen.

No, we need a recent U-Boot in order to boot, and such a uboot will
setup the memory node anyway.
